New Old Stock (NOS)
New Old Stock deck pocket watches are high precision vintage timepieces that were manufactured decades ago but remained unworn, unsold, and unused in their original packaging. A “deck watch” specifically refers to a pocket sized marine chronometer used for precise navigation at sea.

Deck watch
A deck watch (or deck chronometer) is a specialised “tool watch” designed for extreme accuracy. Ship officers and captains used them to carry the precise time from the ship’s main marine chronometer (kept safely below deck) to the upper deck for taking celestial sightings.
They often look like oversized pocket watches, with silver or heavy duty cases that resist water and salt air. They were far more accurate than standard civilian pocket watches and were often tested and certified by official observatories.
